Question

a side of the triangle below has been extended to form an exterior angle of 136°. find the value of x.

Explanation:

Step1: Identify supplementary angles

The 136° angle and $x$ form a linear pair, so they are supplementary (sum to 180°).
$x + 136^\circ = 180^\circ$

Step2: Solve for $x$

Subtract 136° from both sides to isolate $x$.
$x = 180^\circ - 136^\circ$

Answer:

$44^\circ$
